Given: Data relating to the types of bridge failure caused by hazard events were recorded over a period of $50$ years and are shown in the table below.

$\backslash$table$[[$Bridge Type,$\backslash$table$[[$Seismic$],[($E$)]],\backslash$table$[[$Overload$],[($O$)]],\backslash$table$[[$Vehicle$],[$Collision$],[($VC$)]],\backslash$table$[[$Flood$],[($F$)]],\backslash$table$[[$Total No$.],[$Bridges$],[$Failed$]],\backslash$table$[[$Total No$.],[$Bridges $>50],[$yrs $($N$)]]],[$Steel Girder $($SG$),10,5,8,15,38,500],[$Concrete $($C$),5,3,0,5,13,50],[$Truss $($T$),1,1,3,2,7,65],[$Suspension $($S$),5,0,0,0,5,10],[$Total$,21,9,11,22,63,625],[$Analysis period, t$=50$ years,,,,,,$]]$

Find Using data in the table above, provide the following graphical descriptive statistics:

$3-$D Column Chart illustrating the number of failures by hazard and bridge type within the $50$ year period. $(5)$

$2-$D Pie chart illustrating number of bridges older than $50$ years by bridge type. $(5)$
